Hoʻomaka i nā mea maka no ka hana ʻana i nā bolts ikaika kiʻekiʻe

Hoʻokaʻawale mākou i ke kila kalapona haʻahaʻa, ke kila kalapona waena, ke kila kalapona kiʻekiʻe a me ke kila kila e like me ka ʻike kalapona i ke kila kalapona.

1 ʻO ke kila kalapona haʻahaʻa C% ≤ 0.25% ka mea maʻamau i kapa ʻia ʻo A3 kila ma Kina. Kāhea ʻia ʻo 10081015181022 ma waho. Hoʻohana nui ʻia no nā bolts Grade 4.8,ʻO nā hua Gr4, nā wili liʻiliʻi a me nā huahana ʻē aʻe me ka ʻole o nā koi paʻakikī. (E hoʻomaopopo: Hoʻohana nui ʻia nā mea 1022 no ka wili ʻana i nā kui.) ʻAʻole kūpono kēia mea nonā kī ikaika kiʻekiʻe.

2.Medium kalapona kila> 0.25%, C1035 35 #, 35ACR, ia noHex bolts papa 8.8nā nui, akā no nā nui nui a me nā ʻāpana wela wela, ʻaʻole hiki ke hoʻohana.

3 Ke kila kalapona kiʻekiʻe C%>0.45%. ʻO ka maʻamau, no kēia kilaGr8.8 mau kī, nā nui hoʻoheheʻe wela.

4 Alloy kila: hoʻohui ʻia nā mea hoʻohui i ke kila kalapona maʻamau e hoʻonui i kekahi mau waiwai kūikawā o ke kila, e like me 40Cr, 35CrMo, 42CrMo., SCM435, 10B38. Hana ʻia nā ʻili Fangsheng i ka SCM435 chrome molybdenum alloy steel, ka mea nui i haku ʻia me C, Si, Mn, P, S, Cr a me Mo. Hoʻohana kā mākou hui i ka 40Cr a i ʻole 35CrMo i ka proudce10.9 mau kī, 42CrMo, SCM435 e hanaGr12.9 bolts.

Inā hoʻohana ka hale hana i nā mea maka hewa, ʻaʻole lākou e hoʻokō i ka pae i makemake ʻia i ke kaʻina hanalapaʻau wela, a ʻaʻole kūpono ka maikaʻi
Ningbo Zhongli bolts manufacturing co.ltdua hoʻokumu ʻia i ka makahiki 2003, ʻo ia hoʻimea hoʻolako bolts ʻoihana ma Kina. Loaʻa iā ia nā ʻenehana ikaika a me nā hui hana i nā makahiki he nui i hala, ʻoi aku ka maikaʻi a paʻa, ʻo ka nui o nā huahana he ikaika kiʻekiʻe DIN a me ANSI maʻamau kiʻekiʻe bolts, Hex nuts, nā mea holoi holoi.
